Slices

Slices are UI templates that can display rich, dynamic, and interactive content from your app
from within the Google Search app and later in other places like the Google Assistant. Slices
can help users perform tasks faster by enabling engagement outside of the fullscreen app
experience. You can build Slices as enhancements to
App Actions.

Support for Slices is built into Android Jetpack and can
extend all the way back to Android 4.4, reaching approximately 95% of all Android users.
